摘　　要：介绍一种基于α能谱分析的放射性气溶胶监测仪的设计。仪器设计根据天然放射性气溶胶与人工放射性气溶胶α能谱分布特性的不同,采用多道脉冲幅度分析技术消除天然放射性对人工放射性气溶胶监测的影响。本文着重阐述仪器硬件的设计方案和关键技术的解决,对此类放射性气溶胶监测仪的研制提供一定借鉴。A hardware design of radioactive aerosol monitoring system based on alpha spectrum analysis is presented. According to the peak-position distribution of alpha spectra in artificial is different from that of natural radioactive aerosol, the technique of multi-channel pulse amplitude analysis is applied to reduce the interference resulted from natural radioactive aerosol in the monitoring of artificial radioactive aerosol. We provide highlights of the designing scheme, as well as solutions for key technologies in this paper, which can provide consult to the development of this kind of radioactive aerosol monitor.
